The bill titled "An Act authorizing the city of Holyoke to prohibit use of SGARs" allows the city of Holyoke to regulate the use of second generation anti-coagulant rodenticides (SGARs) through local bylaws or health regulations. This includes the authority to prohibit the use of SGARs by licensed commercial applicators, as defined in the Massachusetts regulations. The bill explicitly states that it overrides any conflicting provisions in chapter 132B of the General Laws or other laws.

Additionally, the bill repeals any inconsistent provisions from Chapter 438 of the Acts of 1896 and Chapter 327 of the Acts of 1936. It also grants the General Court the ability to make clerical or editorial changes to the bill, provided that any amendments are approved by the Mayor and City Council of Holyoke before enactment. The act is set to take effect immediately upon passage.
